Question 1152653
it will be f(x)=1/(b-a), b=120 and a =90 units min
for <110 min it would be 20/30 or 2/3 prob.
at least 100 min would be 20/30 or 2/3
between 95 and 110 min is 15/30 or 1/2

greater than/less than include the number itself in a density function, since everything reduces to a dimensionless point.
